Introduction of XLPE Insulated Power Cable
XLPE cable constitutes the best cable for transmission and distribution lines because of its excellent electrical and physical properties. The excellent resistance to thermal deformation and the excellent aging property of XLPE cable permit it to carry large current under normal(90℃), emergency(130℃) or short circuit(250℃) conditions.
XLPE cable withstands smaller radius bending and is lighter in weight, allowing for easy and reliable installation. Furthermore, the splicing and terminating methods for XLPE cable are simpler in comparison with other kinds of cables.
XLPE cables can be installed anywhere without special consideration of the route profile (height limitations) since it does not contain oil and thus is free from failures due to oil migration in oil-filled cables. XLPE cable does not generally demand a metallic sheath. Thus it is free from the failures peculiar to metallic-sheathed cables, such as corrosion and fatigue.
Using range of XLPE Insulated Power Cable
This product is for rated voltage (U0 / U) 0.6/1-26/35 kv power line transmission and distribution
Characteristics of XLPE Insulated Power Cable
1. The highest rated temperature of the cable conductor is 90 ° C, the short circuit (the longest duration of no more than 5 s), highest temperature of the cable conductor does not exceed 250 ° C.
2.The ambient temperature should not be less than 0 ° C when laying cables.
3.Allowed bending radius of laying: single-core cable is not less than 15 times the cable diameter; multi-core cable is not less than 10 times the cable diameter.
Application of XLPE Insulated Power Cable
Copper (aluminum) core cross-linked polyethylene laying indoors, channels and tubes, but also buried in the loose insulation of PVC sheathed power cable soil, can not afford external force
Copper (aluminum) core cross-linked polyethylene laying in the ground, can withstand the role of mechanical force, but unable to bear PVC insulation tape armored PVC sheathed power cable large pulling force.
